We are offering here the Plywood of various types that is a material manufactured from thin layers or plies of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another. It tends to be extremely strong, though not very attractive, and is treated in many different ways depending upon its intended application. It is made by sticking three or more boards (veneers) of wood together with some sort of adhesive. The explanation does not need to be much more complicated than that. They are used for floors, walls, roofs and garages in residential construction. Plywood is a material that should be able to withstand full weather exposure and a lot of stress.
